小编igo*_*die的帖子

我有以下布局：

<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

  
    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"

if [ "$1" = "" ]
then
       echo -n "Gib das Startkapital ein: "
       read kapital
else
       kapital  = $1
fi

echo $kapital

当我说kapital = $ 1时它说这个变量不存在:

$ sh zins.sh
zins.sh: 16: zins.sh kapital: not found

所以我有这个班级"会员":

package pkgData;

import java.io.Serializable;

public class Member implements Comparable<Member>, Serializable{
  /**
  * 
  */
  private static final long serialVersionUID = 1L;
  private String name;
  private String city;

  public Member(String nameOfMember,String location) {
      super();
      this.name = nameOfMember;
      this.city=location;
  }


  public String getNameOfMember() {
      return name;
  }

  public String getLocationOfMember() {
      return city;
  }

  public void setNameOfMember(String nameOfMember) {
      this.name = nameOfMember;
  }


  @Override
  public String toString() {
      return name +", " + city;
  }


  @Override
  public int compareTo(Member o) {
      int …
